GATE.

iii-ECIFICATION' forming part of Lettezs Patent No. 341,896, dated May 18, 1886.

Application filed DccemherS, 1885. Szrial No. 185,060. (Model) To all whom it may concern:

Be it known that I, VVILLIAM D. ELLIS, a citizen of the United States, residing at Blaine, in the county of Boone and State of Illinois, have invented certain new and useful Improve ments in Gates,- and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The invention relates, generally, to that class of gates which slide laterally on a track and are provided with friction'rollers.

The features of invention will first he described in connection with the drawings, and then pointed out in the claims.

Figure l of the drawings is aside elevation showing the gate closed; Fig. 2, a similar view showing it' half open; Fig. 3, a similar view showing it entirely open; and Fig. 4 is a View in detail of several parts. Fig. 5 is a vertical cross-section showing the two in clined tracks.

In the drawings, A represents the gate, A A the gate-posts, B, the track, and B B the track-posts.

-O is a guide-post, which is parallel to the gate-post A both posts being provided with the opposite guidc-rolls, D, between which passes the gate.

E E are flanged rollers provided with the trunnions c e, and G G yokes fastened on opposite sides of the gate-rails, parallel to each other, and carrying the tracks 9. One of these yokes is placed as near as possible to the rear end of the gate, while the other is about four feet therefrom in a gate having a length of twelve feet. The flanges of the rolls embrace or receive between them the track B, while the auxiliary tracks g come into contact with the trunnions e e, which pass from end to end of said tracks 9 in the same time that the rollers pass over the track B, the circumference of the trunnions bearing the same relation to the length of the tracks g that the circumference of the rolls bearsto the length of the track B. The gate is made considerably heavier at the rear end, so that it will press down on the end roll and up on the other, thus keeping the rollers on the track. The auxiliary tracks 51 are inclined from the middle toward ff, and H H are fixed posts having horizon tal arms h, carrying pulleys 71 h.

I J are end-weighted cords or ropes passing over the pulleys/h, so that the gate may be opened or closed by pulling on one or the other of the cords.

K is a block beveled downwardly from the inner side of the gate-post A, so as to re ceive the beveled end a of the gate, and thus support the front end of the gate with'sufficient friction to render any gate-latch unnecessary, and at the same time to prevent sagging. The beveled end of the gate may have side flanges, one passing on each side of the block, and outwardly flared at the front ends.

K is another block on an upward incline from the gate-post A, and arranged at one sideofit. On this block runs a friction-roller, it, under the front end of the gate, so that when the gate is open the front end is supported and cannot sag. In some gates the yokes G may have straight auxiliary tracks 9, while my rollers, yokes, and tracks may be employed with picket, slat, and other forms of gate with equal advantage.

Having thus described all that is necessary to a full understandii'ig of my invention,what I claim to be new, and desire to protect by Letters Patent, is-

1. The sliding gate provided with yokes G, having double-inclined tracks g, in combination with the flanged rolls having trunnions resting on the incline, and with a stationary track. substantially as and for the purpose In testimony whereof Iaffix mysignature in specified. presence of two Witnesses. 2. In a sliding gate, the combination of a bottom rail having the subjacent roll t, the WILLIAM D. ELLIS. 5 posts A A and the two inclined blocks K K, writnesseg the latter constructed and arranged with respeet to the posts substantially as and for the PETER GRAMER,

purpose set forth. AMOS PIERCE.
